Frankly, Bashiok's reasoning is ludicrous.
You may think we’re trying to be underhanded, but the reality is we’re trying to help people be more efficient with their play time. What most people don’t realize is that if they get and complete an in-progress run, the next time they queue they will preferentially be placed into a fresh instance.
I'd love to be more efficient with my playtime. I'd like to sit in a queue, while doing dailies, until I get a fresh run, and do ONE RUN of the LFR per week. Two queues, and two and a half runs, is *not* the most efficient use of my playtime...especially when I have alts that *also* need LFR runs. You cannot remotely attempt to tell me that multiple runs is somehow more efficient than a single run!
That doesn't even remotely pass Logic 101. Doing something once takes less time than doing something twice. Seriously, the waits after Blackhorn weren't remotely as bad as having to queue three and four and five times while playing Boss Roulette...and anyone who says they were is smoking something.
What everyone should be doing, to be the most efficient, is joining and sticking with their runs to completion.
Happy to do this. I never left an LFR run during Cata that wasn't for a legitimate RL emergency...but there's zero reason to stay in an LFR run if I've already looted a boss and can't loot him anymore, especially when my spot can be filled by someone who perhaps can.
In reality, this system makes the problem WORSE by putting people in at boss #3 and #4, because then on their next run, in order to use their time "efficiently", they're basically encouraged to *leave* after boss #2 and find something that isn't a waste of time, thereby creating another hole to be filled at boss #3 for the next person, etc, etc, ad nauseum...
The patch has only been out a couple days of course, but personally I think there are some people who don’t realize yet how an in-progress run, and that extra Valor, can directly translate to improved items through the new upgrade system.
So, since upgrades are currently removed, this system of getting shoved in an in-progress run should be going away, yes?
Edit: Look... If you REALLY want people to stay until the end of an LFR run, don't give out the loot until after the final boss is dead. (But don't loot-lock people to any bosses until that point, either.) But stop penalizing people who don't have the time to queue twenty times a week trying to get four bosses dead. That's just cruel and unusual punishment.
